EdX expands range of institutions that can offer free online courses

EdX's open online education system has drawn a lot of interest -- enough interest that the non-profit has just loosened up its membership structure to allow for more participants. The revamp lets 12 additional organizations offer free internet-based courses, including schools as well as non-academic outlets like the International Monetary Fund, the Linux Foundation and the Smithsonian Institution. Details of the new programs aren't available beyond the Linux Foundation's plans for an introductory Linux course, but edX's move is bound to improve the diversity of things you can learn without spending a dime on tuition.
